To (:ZZ wZzom it may concern:

Be it known that I, GEORGE Bes'rnm, a

fiiiizen of the te -i r s ing at Itiarion. in the county of- Marion and Y State oif O hio, haveinven ted a certain new and useful Improvement in Reed- St0ning"Mafend exact description.

The present invention relates to a machine which are used in connection with silk weavns The object of the invention 1s to produce ,amachine inwhich a tool such as a honing stone may be given a movement transversely ofthe objecton which it is working as for instance a feed, and additionally to' provide mechanismuwhereby the honing stone or a tool carried by a suitable holder nay be raised i'romthe workat the end 0f a working stroke, and theworking stroke may be i varied. Additionally, the'machine provides a mechanism whereby the carrier or support forthe honing stoneor other tool will be .completely lowered into contact with the object beingworlzed ,on, each time'the stone .isbroughtinto engagementwith the reed or other ob ect and so compensate for anyv wear of the stone, without requiring any actual adjustment of the stone.

, Otheiqobjects will appear as the descrip- -.tion proceeds.

bolted together constitute what will herein fbefternied a frame. One ofthe side memhersis-previded' with an o'iiset member indiwhieh is particularly adapted andintended .ior use-in. the stoning or honing of reeds cated-att' in which is formed a suitable opening in line with another opening formed in the side member 2 and adapted to receive shaft Sand to form bearings for said shaft. it one end or the shaft is a crank'rneniber i The shaft 5 has secured thereto a bevel gear 9 which meshes with a bevel gear 10. This gear 10 is carried upon afshaft 11 which is mounted in bearing members 12 and-1 3! At theend of the shaft-ll there isv a disk 14- to which is pivotally secured one end of the connecting rod 15. The opposite end of this wnnecnng rod 15 is pivotally mounted in slot 16 of the lever'le this Construction being for the purpose of pro- 7 vidiiig an adjustment between the connecting rod 15 and the lever 16 to "regulate the extent of movement of the lever '16 by the connecting rod 15. The lever '16 at its lo .v"erend is loosely mounted upon a shaft 17 and this shaft has secured thereto a'ratchet wheel lS. Adjacent the lower end of the lever 16 there'is a pin 19 upon which is pivoted a double pawl 2O having anextendg g r 1. By moving the. arm 2lto one side or the other, either end oi' thedouble pawl 20. may be moved into engagement with the: ratchet wheel, 18 so that" the ratchet wheel may beturned in either direction in accordancewith whiohever end of the pawl is in engagement with the ratchet wheel.

Theshaft Ll? carries a pinion 22ivhich is adapted. to cooperate with a rack 23 carried upon the underside of a bed 24:- This bed is mounted upon two spaced supporting track membersindioated at 25 and the bedis adapted ton ove upon these track members and transversely with respect to the frame A of the machine. This bed QL is adapted to receive the articlewhich is to beworl :ed on as flinsta-nce a reed which is indicated As will be readily understood, the bed will be moved intermittently by the mechanism before described and the direction of movement or the bed may be reversed by changing the pawl engagement with the ratchet wheel 18. I

Mounted between the side members 1 and 2 is a head 26 which is shown in detail-in Fig. 10. This headv comprises, substantially, a. top portion 26 and side portions 26 ()n the sideportions are extending members 26 which extend into grooves 27 that i are formed in the- side members 1 and 2. These members 26may be plain pins or they may be rollers seas to reduce the trio-1 1 tion. Extending rearwardly from the head 26 are rods 29 andSO disposed adjacent the side members 1 and 2, and these rods are adapted to extend through openingsin blocks 1 and 2? which are carried by the members 1 and 2 respectively. The grooves 27 serve to support the head 26 and in part to guide the same in its reciprocating movement which is about to be described, and the rods of the machine.

. ed upon the top of the head 26.

29 and 30'also serve toguide and support the head.

* The head 26 atuthe rear thereof is prothe present instance, the tool holder is adaptedtoholda honing stone, theterm tool is used in the broad sense and is inclusive of anything which can perform work upon the article orobject carried by the bed 24;.

The tool holder comprises a transversely extending member 31' which atits side edges is provided with grooves 32 and these grooves are adapted to cooperate with guide strips .26 and 26 that are carried upon'the .inner side of the side members 26 of the head 26. The tool carrier 3i. so'far as its mounting is concerned may freely slide upon the members 26 and26 of the head 26. The tool carrier as before stated is in the present instance particularly adapted to receiveand retain a honing stone which is indicated at v Secured to the memberiil is an upwardly extending strip-like member 64 which re; tends behind the head 26 and above the same and at its upper end there is a transversely extending member 35; This member is provided with openings through which openings extend pins 36 and 3'? which are mounting the pins and 37 are springs 38 and '39 and these springs extend between the top of the head 26 and the underside of the .moreclearly shown in Fig.6. I

portion or the member 4-3 has a recess '43, the purpose Depending" irom the member 43 is a Surround transversely extending member 35. These springs serve to cushion the descending movement oi the tool carrier and the honing stone carried thereby when thesame is released. after having been moved upwardly as will'iater'be described.

Upon the rear portion of the tool holder 81 and extending above the same are guiding members which are indicated at 40 and ll. These members provide guide grooves such as indicated at 4:0 and t1, the side walls or these grooves being provided with ratchet teeth 4:2. Occupying the guide grooves 20 and :1 an operating member 43 which has an upwardly extending and downwardly bent portion This operating member is The lower ot which will be later described.

spreader 45, the upper surface of which has oppositely slanting portions. This spreader is carried by a depending rod 46 which is pivotally mounted on the member l3 as indicated at 457. f

Behind the member- 43 is a flat strip-like member 4:8 which at its lower-end has two oppositely disposed pawls 4L9 pivoted thereto. (See Fig. 9). These pawls extend sidewardly toward the ratchet teeth42 and as will be seen from F 6 the spreader lies just below thepa-wls 4:9 and in'position to cooperate with and spread the""pawls 4:9

when the spreader eievated. When the pa'wls 4.9 are spread they will be moved into contact with certain of the ratchetteeth +22, and this mechanism comprising the pearls and the spreader in effect forms a clutch mechanism which joins the tool carrier to the operating member 43 so that when the member is elevated, as will be later described, it will carry with it the tool holding member. The strip at its upper end is provided with cross member L8 which is provided with openings'to receive the pins 36 and 3! so that the movement of the memlcer aS'and the parts associated therewith is guidedhy the engagement otthe pins with the member 48. I

Extending transversely of the head and behind the head is a member 50. This memher at its opposite ends has arms, one of which is indicated at 51 and these arms carry extensions in the form of blocks which are shown indotted lines at52 in Fig. 5', which extensions lie within the oppositely disposed slots which are formed in the side members 26 or the head 26, one or which slots is indicated at 26 in Fig. .11. These blocks 52 carry outwardly projecting guide rollers 53 which occupy grooves54; and '55 in oppositely disposed track members 56 and 57.

- The track members 56 and 57 each occupy a groove formed in the' side members 1 and 2, respectively, and are so mounted that they formed. 53-operate inthe cam grooves 54 and 55. As the head '26 is'recip'rocated and with it At their 1 forward end the track this member has mounted in it a screw 60.

Thescrew extends through a threadedtboss 61 which: iscarr-ied ona transversely extended bar 62 which is secured to the front portionsof theside membersl and 2. Byturning-thescrew 60,the track members '56 and -57fmaybezmoved forward and back-ward .in to' any 'adjusted positionjwith respect to the side members land 2 of the frame.

in Fig. one of the trackmembers is cam groove '54. As will be seen this groove has a straight portion 54 and inclined portion-54 and an upper straight portion 54. The groove in the track '57 is similarly Itwill-be recalled that the rollers the'parts carried thereby, the rollers 53 move through the straightportions 54 of the 1 grooves inthe track members 56 and 57 and,

when they reach the inclined portions 54 ofthe grooves, they move upwardlytherein 1 and this causes the member 50 to beelevated with respect tothe' head. When this member 50 iselevated itengages withthe portion44 of -the operating member 43 which raises the operating member causing the spreader 45 to engage with the p-awls 49 andpushing them into engagement with the ratcli et teeth carried by' the sides and 41 which form a part of the tool holder, and as the spreader is elevated with the member 43 the tool holder is'carried along and so elevated from the work upon which the tool and' 39 and so the honing stone'is in carried thereby has been operated.

The foregoing movement takes place during a rearward excursion of 'thehead and of course'wlien 'the rearward excursion of the 'head-has been completed and the forward 1 excursion commenced, the rollers I 53 will presently return tothe-lower portion of the cam gr'ooves'in whichthey operate and thereby relieve the pawls-49yso that the tool carrier'drops'by gravity against the springs 38 proper position for a working stroke. 7

As-before described, the track members 56 are moved outwardly from'the position in fwhich they are shown in Fig. 2, the tool holder will be elevated sooner,-with respect 'to the reciprocation of the head than would be thecase with the track membersin'position as shown in thedrawing.

rai sing" of the tool holderfis of' importance formipressure upon the honing stone will 'beobvious the tool holder may be made honed.

ing.

tool-holder maybe-made along or-i short stroke.

It will be -notedfrom the foregoing description that when the tool holder is in its workingz position,ithat:isi tozsay, when the tool carried therebyis in position'to operate upon the object? to be worked on,"the weight of the tool holder is upon thetool or in. this shown and in it a cam 'groove, which is the case, the honingstone, thereby giving a urgiof a desired orany proper weight to give the desired pressure on the-honing stone in-order for the honing stoneto do its efficient and proper work; I I

The mechanism which has heretofore been described; by which the tool holder is elevate'dis such that the tool holder is entirely releasedwhen it is on its operating stroke so that as'thehoningstone may wear, it requires no adjustmentof the honing stone or the tool holder, this being automatically taken care of by the fact thatthe gripping -pawls49 may grip or'engage with any one a of the teeth 42 which form a part of the tool holder. This isavery importantresult inas much as 'it secures'an' absolutely uniform honing action on the reed which is being 'l Vhile inthe drawingI have shown a handoperative machine, that is to say the shaft 5 is'operated by hand, it will be understood that I 'donot mean: to confine myself in this respect, if power operation 'be-found desirable.
